OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 314,360, dated March 24, 1885.

(No model.)

If 0 all whom, it may concern:

This invention relates to that class of oil-,

cups which are used for supplying oil to bearings of machinery within steam-chambers; and the object of the invention is to utilize condensed steam to cause the oil to flow into the delivery-pipe, to control the amount of steam-supply and the amount of oil-supply, and to see the amount of oil supplied.

To this end my invention consists in the construction and combination of parts forming an oil cup, hereinafter described and claimed, reference being had to the accompanying drawing, which is an elevation of my invention, partly broken away to show the interior.

A represents the body of the oilcnp, into which oil is to be introduced through the opening shown closed by a screw-plug, B.

L is a screw-plug by which the device is to be attached to an engine-cylinder or other steam-passage which is to be oiled. This plug is a tube through which the oil may pass.

J is a stop-cock, by means of which the passage through the pipe or plug L may be closed to stop the exit of steam when desired.

D is a pipe leading from the interior of the oil-cup near its top toa glass passage, Lwhere it is provided with a nozzle, G, from whichv the oil drops through the passages I and L into the cylinder. The passage I is formed of glass, secured in a cage of metallic bars, H, in order that the drops may be seen and their rate of delivery noted.

0 is a steam-tube extending from the possage I to the interior of the cup A, its upper end being higher than the upper end of tube D, in order that the oil may always find exit through its proper passage before it reaches the height of the steam-pipe.

F and E are stop-cocks, the one to regulate the admission of steam and the other to regulate the flow of oil.

In operation, first open the cocks J and E, then gradually open the cock F. The steam slowly discharging from the tube 0 into the cooler oil-chamber will condense into water and settle drop by drop into the oil. The water being heavier than oil will sink therein, and the cup being full of oil to the top of the tube D, a drop of oil will be forced over into this dischargetube for every drop of water that condenses in the oil-cup. Thus all the oil in the cup will be gradually displaced by water, and be delivered, as before described, through the tube L to its destination.

K represents a cock,by which the water may be discharged from the oil-cup.

The transparent tube or passage I below the delivery of the oil-pipe is a great convenience in enabling the operator to see exactly at what rate the drops of oil are falling into the cylinder, and by this means he may see whether the oil begins to deliver when he opens the steam-cock F. Sometimes an oil-cup will become so hot as to condense the steam very slowly, or even not at all. Then oil will not deliver, even though the steam-cock is open, and the steam should be shut off entirely by cock J until the oiler cools.

The object of the nozzle G is to so contract the pipe D that oil shall be delivered therefrom in drops in order that the rate of delivery may be seen through the tube I by the operator.

\Vhat I claim as my invention,and desire to secure by Letters Patent, is

The combination of the oil-cup A, the hollow screw-plug L, the cage H, securing the cup and plug together, the glass tubeI, adjoining the hollow screw-plug, the steam-pipe 0, connecting the upper end of the glass-tube chamber with the upper end of the cup-chamber, the drip-pipe 1), connecting the cup-chamber with the glass-tube chamber, each of its ends being lower than the corresponding ends of the pipe 0, and its lower end provided with a reduced nozzle, G, the stop-cocks E and F in the tubes D and C, respectively, and the plug B in the top of the cup, substantially as shown and described, whereby both pipes O and D communicate with the same chambers at different levels, and whereby the action of both pipes may be observed.
